PROPHESYING DOOM and destruction during a time of peace and prosperity does not make one popular with the ruling elites.  

Amos discovered this while declaring God’s judgment on the northern kingdom of Israel during the reign of Jeroboam II (reigned 793–753 BC), the time of Israel’s greatest power. The prophet was confronted by Amaziah, the priest of Bethel, and told to flee to the southern kingdom of Judah, which prompted the Lord to tell the priest that his wife would be forced into prostitution, his children would fall by the sword, Amaziah would die in a foreign land, and Israel would be taken away into exile.

These things did come to pass in 732 BC, when Assyria conquered Israel and captured the capital city of Samaria.

We also discuss the strange reference in the Septuagint to “King Gog” or “Agag, the king” in Amos 7:1, which is quite different from the ESV rendering, “the king’s mowings” (or the NET translation, “the royal harvest”). Apparently the LXX translators didn’t know what to make of the literal Hebrew (“the mowings of the king”) but recognized the context as a prophecy of destruction. 

Agag was the Amalekite king spared by Saul (and then executed by Samuel). In the book of Esther, Haman, the Persian official who plotted the genocide of the Jews (and thus a symbol of hatred toward Jews), was called “the Agagite.” Gog, a reference to Ezekiel 38–39, is the great end times enemy of God—essentially the Old Testament conception of the Antichrist. 

Thus, the Septuagint translators who struggled to interpret an archaic reference simply plugged in a similar-sounding word (Gog or Agag) that preserved the context of a prophesied supernatural enemy of God and Israel.
